Lately (for several weeks) I have been having trouble printing web pages with bold headings (Not Headers... Headings) in their pages. For example - recipes. The bold text which is usually also a larger font, is either missing completely, or just a series of dots. It looks just fine in the print preview (I am on a mac, running High Sierra 10.13.6) and the problem exists whether I use the webpage print dialog or my operating system dialog. I have tried both of my available printers and it happens on both printers, so it isn't a problem with my printers (I thought it might just be my old HP P1505) I have also tried saving the page as a pdf through my print system dialog - the text problem exists there as well. If I use Safari (I prefer Firefox, but if this is going to continue, then I'll have to go back) everything is fine. (see the attached image - Firefox on the left, Safari on the right) So there seems to be something in Firefox that has recently stopped allowing these fonts to make their way through from the screen into the print system.
